Evaluation of a school-based health and well-being program for adolescent girls

Background: The primary aim of this pilot study was to evaluate the feasibility and impact of a school-based health and well-being program (Health and Wellbeing for Girls: HWBG) on adolescent girls’ well-being, mindfulness, screen-time and physical activity. Method: The HWBG program was evaluated using a group randomised controlled trial (RCT) in one secondary school. A convenience sample of female students in Grade 8 (mean age: 14 ± 0.5 years) was recruited for the study (n=4 classes; 89 girls). The 20-week multi-component HWBG program, guided by Self-Determination Theory and Acceptance and Commitment Therapy, was designed and delivered by a member of the research team. Process evaluation measures of recruitment, retention, adherence and satisfaction were used to determine program feasibility. Preliminary efficacy of HWBG for improving mental and social health, screen-time and physical activity was measured and analysed using linear mixed models. Results: Significant group-by-time improvements and medium effects resulted for mental (p=0.04, d=0.45) and social health (p=0.02, d=0.5). No significant intervention effects were found for levels of physical activity and screen time. Participant ratings showed high levels of perceived benefit and enjoyment as indicated in the evaluation data, (mean rating of 4.44 out of a possible 5.0) when asked whether the program was enjoyable. Conclusion: In addition to improving pro-social outcomes and psychological wellbeing levels in adolescent females this study provides preliminary support for HWBG as a potentially feasible, efficacious and enjoyable program suitable for use with adolescent girls in the secondary schools setting.
